how to generate wsdl through wsgen as ant task

try to generate jax-ws wsdl file from a java application service through wsgen as ANT task. Ant's taskdef itself giving me lots of class not found exception. Every first time it gave class not fount for "com.sun.tools.ws.ant.WsGen" then added "jaxws-tools-2.1.7.jar" in class path. After this , it gave class not found for "com/sun/istack/tools/ProtectedTask" then added "istack-commons-tools-2.7.jar". Now it's giving class not found for "com/sun/tools/xjc/api/util/ToolsJarNotFoundException"

I am sure , I am not following right path.

here is build.xml

<?xml version="1.0"?>
<project name="Application Services" basedir="." default="compile">
<property file="build.properties"/>
<path id="external.projects">

    <fileset dir="/scratch/softwares" includes="*.jar"/>

</path>

<taskdef name="wsgen" classname="com.sun.tools.ws.ant.WsGen" classpathref="external.projects"> 

</taskdef>


<target name="compile" depends="clean,init">

      <javac destdir="${build.dir}" srcdir="${src.dir}" classpathref="external.projects"/>
</target>
<target name="packaging" depends="compile">
    <mkdir dir="${jar.dir}"/>
    <jar destfile="${jar.dir}/application.services.jar" basedir="${build.dir}"/>
    <wsgen 
        sei="webservice.interfaces.student.IStudentApplicationService"
        destdir="${jar.dir}" cp="external.projects" resourcedestdir="${jar.dir}"
        sourcedestdir="${jar.dir}" genwsdl="true"
        />
</target>
</project>
Solution

  • Debugging dependencies between jars can drive you demented......What your ANT project requires is a dependency manager, for example Apache ivy.

    A second problem I noticed is that you're running a very old version is jaxws-tools, released in 2009. Since then there have been lots and lots of updates.

    Example

    Demonstrates how ivy can be used to create a managed classpath for the wsgen task.

    <ivy:cachepath pathid="wsgen.path">
  <dependency org="com.sun.xml.ws" name="jaxws-tools" rev="2.2.10" />
</ivy:cachepath>

<taskdef name="wsgen" classname="com.sun.tools.ws.ant.WsGen" classpathref="wsgen.path"/>

    build.xml

    <?xml version="1.0"?>
<project name="Application Services" basedir="." default="packaging" xmlns:ivy="antlib:org.apache.ivy.ant">

  <available classname="org.apache.ivy.Main" property="ivy.installed"/> 

  <target name="install-ivy" description="Install ivy" unless="ivy.installed">
    <mkdir dir="${user.home}/.ant/lib"/>
    <get dest="${user.home}/.ant/lib/ivy.jar" src="http://search.maven.org/remotecontent?filepath=org/apache/ivy/ivy/2.3.0/ivy-2.3.0.jar"/>
    <fail message="Ivy has been installed. Run the build again"/>
  </target>

  <target name="resolve" depends="install-ivy" description="Use ivy to resolve classpaths">
    <ivy:cachepath pathid="wsgen.path">
      <dependency org="com.sun.xml.ws" name="jaxws-tools" rev="2.2.10" />
    </ivy:cachepath>
  </target>

  <target name="packaging" depends="resolve">
    <taskdef name="wsgen" classname="com.sun.tools.ws.ant.WsGen" classpathref="wsgen.path"/> 

    <wsgen 
        sei="webservice.interfaces.student.IStudentApplicationService"
        destdir="${jar.dir}" cp="external.projects" resourcedestdir="${jar.dir}"
        sourcedestdir="${jar.dir}" genwsdl="true"
        />
  </target>

</project>
